VEHICLE DRIVE MECHANISM.

To al? whom it may concern Be it known that I, WILLIAM EMIL Boon', a citizen of the United States of America, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Vehicle Drive Mechanism7 of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to vehicle drive mechanisms and consists in the peculiar con--l struction, arrangement and combination of a motor and compensating gearing as hereinafter set forth.

In the drawings, the motor and compensating gearing is shown in longitudinal section as applied to a vehicle drive mechanisml A and B are two alined shafts constituting either the/vehicle drive axle or the jackshaft employed for driving the vehicle wheels.

armature thereof, which is mounted upon al hollow shaft ll. G 1s the drive .smernber of the compensating gearing, which is mounted ,directly upon the shaft F, and engages the bevel pinions Il, which are in mesh with the bevel-gear wheels I" and l respectively upon the shafts A and B. The shaft A passes axially through the hollow or tubular shaft 1*" and is journaled in suitable bearings such as K.

Specification of Letters Patent.

Application filed July 16, 1912. Serial No. 709,653.

`With the construction shown the motor and compensating gearing are housed withinthe axle casing L, at the opposite ends of which are stub axles M, on which the wheels N are journaled. The shafts A and B have mounted at their outer ends the pinions O which are in mesh with the internal gears P, the latter being formed on the interior of the brake drums Q for the vehicle wheels` The' construction described is one which gives an exceedingly compact and convenient arrangement of parts, as the motor is n concentric with the axle or Jack-shaft, and

at the same time drives the latter through the medium of the compensating gearing.

What I claim as my invention is:

1. The combination with an axle casing having oli-set stub axles at its opposite ends, axially alined shaft.c passing through said casing, a. compensating gearing connecting said shafts, an electric motor concentric with said shafts, a hollow armature shaft for said motor sleeved upon one of. said alined shafts, a head mounted on said hollow shaft forming drive member of said compensating gearing, internal gears concentrically arranged on said stub axles, and pinions on the ends of said alined shafts meshing with said internal gears.

2. The combination with an axle casing having oli-set stub axles at its opposite ends, of brake drums provided with integral internal gears concentrically arranged on said stub axles, and means within said axle casing for driving said internal gears.

In testimony whereof I afix my signature in presence of two witnesses.

WILLIAM EMIL BOOK.
